Abstract
Chemically stable, totally organic polymer packings were prepared using newly developed N,N-dialkylacrylamides and their chromatographic properties were examined. The polymer packings were composed of N-methyl N-octadecylacrylamide as a hydrophobic moiety and N,N′-diacrylo-N,N′-dibutyl-1,6-diaminohexane as a crosslinking monomer. The melting points of both monomers were much lower than those of conventional acrylamide and methacryl-amide monomers e.g., N-octadecylmethacrylamide, N,N′-butylenebis(methacrylamide) and N,N′-methylenebis(acrylamide). This property increased misicibility among the monomers and mode possible suspension copolymerization without use of a third solvent, which would have lowered the mechanical strength of the polymer obtained. The hydrophobicity of the particles prepared by suspension copolymerization was controlled by the monomer ratio in the polymerization. In the liquid chromatography, the column with polymer particles showed normal reversed-phase liquid chromatographic separations for alkanes, alcohols and aromatic hydrocarbons. In addition, the packings did not show abnormal adsorption for ionic substances because they were ion free, and showed no peak tailing for carbonyl compounds because of their lack of amide protons.
